Head and body depressed, greatest body depth between level of pectoral-fin insertions and dorsal fin origin. Caudal peduncle deep, compressed posteriorly. Dorsal profile of head ascending steeply from snout tip to nares, then ascending in gentle convex arc to dorsal-fin origin. From the dorsal-fin origin descending in a straight line to posterior adipose-fin tip, then ascending slightly to caudal fin. Ventral profile flat, abdomen slightly convex or concave depending on state of preservation or fullness of intestines.
